I have Lightroom 2.2 on an IMac. I have 4 external drives connected, all of which appear on the desktop.
In attempting to back up my Lightroom catalogue, I get this error message:
"We're sorry, Lightroom was unable to back up the catalogue <filename>. You may wish to check folder permissions or available space."
When I choose a different external drive, I get the same message. All the drives have a lot of free space. Searching the net for this message gives me no hits.
Any advice?
